I can confirm that this issue was SQL related, A fresh install on clean database resolved the matter.

Just out of curiosity (I have posted on BBPress support) and on the off chance someone may have had the same/similar issue over this neck of the woods. Once a forum/group forum post is created, I’ as keymaster cannot, edit,close, stick, merge, trash or spam them? The page simply refreshes with no action taking place.

Fingers crossed, someone, somewhere has had and indeed resolved the matter.

After further examination, it appears that I can edit group forums with no issues whatsoever, it is the sitewide forums that have the blocked actions, I literally can’t do anything with them. Page just refreshes.

I have noticed further issues with buddypress & bbpress, sign up not performing or functioning, no bbpress mails being sent and the complete inability to edit etc ‘any sitewide forums. There may be more issues I have just not checked.
